I specifically added the -D stuff to work around a series of nasty warnings
that appeared in the generated code, because yy_size_t was typedef'ed as a size_t
and then compared against an int.

Apparently the flex version of RedHat 5 produces different output.
Can you tell me which version they ship? I'm using 2.5.35.
